Oz Ben-Joseph was previously a PhD student in the Department of Plant and Environmental Sciences at the Weizmann Institute, researching biomineralization pathways under the guidance of Dr. Assaf Gal. He has a BSc in Biotechnology and Agricultural Sciences from the Hebrew University of Jerusalem and an MSc in Biochemistry from the Weizmann Institute of Science.

In his PhD work, Oz focused on the formation pathways of biological structures made of crystalline material. His work explored the remarkable ability of living cells to create complex 3D crystal shapes, surpassing current artificial fabrication techniques. Oz's research highlights the role of spatial confinement by cellular macromolecules in shaping intricate bio-crystals. He developed innovative imaging methods to identify chemical conditions at intracellular crystal formation sites.
